We were told, and others in our cul de sac. That once it was full we'd get mail delivered to our houses. Not the growing bank of boxes up the hill. Still waiting. Ridiculous we can't get mail delivered. They turn around in our cul de sac!!!!

I Just wanted to give a glowing compliment to my postal lady who always delivers my mail and goes above and beyond to make sure I get my mail. I had an imporatnt letter that was missing my numbers to my address and the postal lady still delivered it to me by name and street only. I called and spoke to Rhonda and I let her know how thankful I am. I'm sure it isn't easy delivering in this providence subdivision with cars parked all over the streets and mailboxes on each side.

Also from the Providence Subdivision. Haven't received mail in almost a week. I'm signed up for informed delivery so I know I'm supposed to have mail. But nothing has shown up for days.

The fact that the mailman who delivers to Providence Subdivision will not deliver mail if a car is parked any where near a mailbox is ridiculous! I have seen my car almost get hit on several occasions because the mailman is too lazy to get out of his/her vehicle is insane- worst and laziest mailman ever.
